First test the battery. It might be OK, but your charger isn't
working correctly. How about charging the battery the old
fashioned way: 14 hours of one tenth the current of the
capacity. This is the correct recipe for NiCd and NiMH
batteries.

Lithium batteries have to be charged until each cell has reached
the final voltage ( normally 3.4 volts ). DO NOT EXCEED THIS
VOLTAGE OR AN EXPLOSION MAY INSUE !!!!!!!!!!

Each cell has to be checked separately. That's why Li packs have
so many contact prongs.

Deep discharge ( under 2.8 volts per cell ) is equally dangerous
and may permanently damage your batteries. A quick check with a
voltmeter may tell you a story......
